C : They have standardized context propagation across services.

D : They provide real-time log analysis capabilities.

Answer: A

Question 2

You have a root span representing an HTTP request and a child span representing a database query executed as part of handling that request. How should the child span reference its parent span?

A : By setting the child span's Trace ID to match the parent span's Trace ID

B : By creating a new Trace ID for the child span

C : By setting the child span's parent_id to the parent span's Span ID

D : By leaving the parent_id field empty in the child span

Answer: C

Question 3

Your distributed application emits logs, traces, and metrics using various legacy libraries. You want to achieve a unified observability pipeline without altering existing log formats. Which OpenTelemetry component should you configure to map and process these diverse telemetry signals uniformly?

A : Implement the OpenTelemetry API directly in each service.

B : Configure the OpenTelemetry Collector to ingest and map the different telemetry signals.

C : Use the OpenTelemetry SDK to replace all legacy libraries.

D : Set up separate backends for logs, traces, and metrics without using OpenTelemetry.

Answer: B

Question 4

How does the trace_id attribute function within multiple spans of a single trace?

A : trace_id changes for each new service involved in the trace.

B : Each span in a trace has a unique trace_id.

C : trace_id is only present in the root span.

D : All spans in a trace share the same trace_id to associate them with the same trace.

Answer: D

Question 5

In an ExponentialHistogram, how are negative values handled?

A : Negative values are mapped by their absolute value into a separate negative range using the same scale as the positive range.

B : Negative values are ignored and not represented in the histogram.
